<p>Light- and heat-responsive adsorbents having both light responsiveness causing reversible adsorption/desorption transition of a solute contained in a solution in dependence on whether they are irradiated with light or not and heat responsiveness causing reversible dissolution/precipitation or swelling/shrinking transition in dependence on temperature, preferably copolymers made from monomer mixtures comprising 1',3',3'-trimethyl-6-(acryloyloxy)spiro(2H-1-benzopyran-2, 2'-indole) and N-isopropylacrylamide. Thus, the invention provides adsorbents which have functions of adsorbing and desorbing a solute in a solution and can recover solutes at high recovery efficiencies.</p> |
